 ==== Knife valve ====
+{{ :pipekit:knife-big.png?128}}
 Also called a gate valve, it is the kind you might find on a large power plant or a hydro-electric dam, their body house a massive metal disc that can be moved in and out of the liquid flow.
 In the real world, these open very slowly.
+They also aren't designed to be partially open, as pressure can bend the gate over time if it isn't fully closed or open.
 ==== Butterfly valve ====
+{{ :pipekit:butterfly-big.png?128}}
 Rotates a large disc inside the pipe they are attached to, they take a lot less space and are cheaper than a gate valve, but they limit the flow a lot and have a much shorter lifespan.
+Large butterfly valves pretty much require a gearbox to get the torque required to break the initial pressure seal.
 //Note: the 1m butterfly valve top fits 30cm compatible flange.//
-Opens with a quarter turn.
 ==== Hydraulic sewage valve ====
-These are typically used in waste processing and other places that handle semi-solids and/or thick products. These aren't actuated directly: They contain a large rubber liner that "closes" when the valve body is filled with air or hydraulic fluid.

+It doesn't look like much, but there valves are typically used in waste processing facilities and other places that handle semi-solids and/or thick products. These aren't actuated directly: They contain a thick rubber liner that pinches itself shut when the valve body is filled with air or hydraulic fluid.
-//Note: The rubber bladder can be seen between the valve body and the flanges.//
+Ideally you want to have one or two smaller pipes connected to this kind of valve to actuate it.

 ===== 30cm & 15cm valves =====
 ==== Butterfly valve ====
+{{ :pipekit:butterfly-small.png?128}}
 Same as its big brother, they rotates a disc inside the pipe they are attached to, they take a lot less space and are cheaper than a knife valve, but they limit the flow a lot and have a much shorter lifespan.
-Opens with a quarter turn.
+Despite being much smaller, the pressure difference can still make it very difficult to open this kind of valve without an attached gearbox.
 //Note: the 30cm butterfly valve top fits 10cm compatible flange.//

-These are not manually operated, and simply contain a flap that prevents the liquid inside the pipe from flowing backward, they usually have just a lid on the front for maintenance.

-In the KDC pipe kit, this is simply a globe valve without a tower or a valve wheel. They are also built in such a way that you can use them as a 3 way manifold, or as a support frame for your own designs, (ex: a flow meter).

+In general this is a good base to build various devices, flow meters, pressure gauges, filters, etc...//
 ==== Globe valve ====
-Normally used to precisely control the flow of the liquid, they typically contain a "globe" shaped plug on the end of a threaded shaft that can be pushed in or out to adjust the flow of the liquid.

+These are typically used to precisely control the flow of a liquid, they contain a "globe" shaped plug on the end of a threaded shaft that can be pushed in or out to adjust the flow of the liquid. They are rarely used as shutoff valves because of how much they limit flow.
 The KDC pipe kit has two versions, one with a visible shaft and shaft housing, and one with a simple valve handle.

 ==== Small Knife valve (10cm only) ====
+{{ :pipekit:knife-small.png?128}}
 The smaller version of the knife valve for 10cm pipes has an integrated tower and the "knife" is exposed when the valve is open.
+Don't pinch your fingers with it!
